User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0 Build ID: 20180105100137 Steps to reproduce: I tried to create a poor man's load tester for my web-application, by starting multiple instances of firefox with separate profiles. 1. Created profiles u0-u15: firefox_nightly/firefox -CreateProfile "u0 /home/ce/dummy_firefox_profiles/u0" firefox_nightly/firefox -CreateProfile "u1 /home/ce/dummy_firefox_profiles/u1" 2. started multiple firefox instances with: firefox_nightly/firefox -new-instance -P u0 firefox_nightly/firefox -new-instance -P u1 3. actually automated the execution using a java application: import java.util.*; public class SplanGuiTest { public static void main(String[] args) throws Exception { Thread.sleep(5000); int profileCounter = 0; LinkedList<Process> processList = new LinkedList<>(); while(true) { profileCounter = (profileCounter + 1) % 15; Process p = Runtime.getRuntime().exec("/home/ce/Programme/firefox_nightly/firefox -new-instance -p u"+profileCounter+" http://127.0.0.1:8080/rap"); processList.push(p); Thread.sleep(2000); if(processList.size() > 3) { processList.removeLast().destroy(); } Thread.sleep(100); } } } Actual results: Firefox frequently died with SIGSEVs in Chrome~dthread, my whole dmesg log is full: [59243.231323] Chrome_~dThread[23590]: segfault at 0 ip 00007fa47c0699ad sp 00007fa47a786af0 error 6 in libxul.so[7fa47bdb1000+482f000] [59245.326985] Chrome_~dThread[23663]: segfault at 0 ip 00007f21f65699ad sp 00007f21f4c86af0 error 6 in libxul.so[7f21f62b1000+482f000] [59245.327328] Chrome_~dThread[24117]: segfault at 0 ip 00007f97474699ad sp 00007f9745b86af0 error 6 in libxul.so[7f97471b1000+482f000] [59245.327991] Chrome_~dThread[23792]: segfault at 0 ip 00007f6743c699ad sp 00007f6742386af0 error 6 in libxul.so[7f67439b1000+482f000] Expected results: No SIGSEV in Chrome~dthread

I see the exact same behaviour with FF 61.0-1 (debian sid package). Even when i start a very small number of instances, it segfaults. Here is a python script (requires selenium) that demonstrates the behaviour with a small number of threads! import time from threading import Thread from selenium import webdriver from selenium.webdriver.firefox.firefox_binary import FirefoxBinary def thread_func(tid): print('thread[%d] started...' % (tid)) # binary = FirefoxBinary('/usr/bin/firefox') binary = FirefoxBinary('/opt/firefox/firefox') options = webdriver.firefox.options.Options() options.add_argument('--headless') driver = webdriver.Firefox(firefox_binary=binary, options=options) driver.get('http://mozilla.org') txt = driver.find_element_by_xpath('//h2[@class="nav-logo"]/a').text print('thread[%d] : %s' % (tid, txt)) driver.save_screenshot('moz%02d.png' % (tid)) driver.quit() threads = [] for t in range(5): threads.append(Thread(target=thread_func, args=(t,))) starttime = time.perf_counter() for t in threads: t.start() for t in threads: t.join() endtime = time.perf_counter() print('timediff = {}'.format(endtime-starttime)) /var/log/messages is filled with these messages: [5251045.491289] Chrome_~dThread[11403]: segfault at 0 ip 00007f82607c747d sp 00007f825f243b00 error 6 in libxul.so[7f82604d9000+4c75000] [5251045.491598] Chrome_~dThread[11046]: segfault at 0 ip 00007fe93bac747d sp 00007fe93a543b00 error 6 in libxul.so[7fe93b7d9000+4c75000] [5251045.491894] Chrome_~dThread[11072]: segfault at 0 ip 00007f7cbd2c747d sp 00007f7cbbd43b00 error 6 in libxul.so[7f7cbcfd9000+4c75000] [5251045.492022] Chrome_~dThread[11430]: segfault at 0 ip 00007f7597ac747d sp 00007f7596543b00 error 6 in libxul.so[7f75977d9000+4c75000] [5251045.492267] Chrome_~dThread[11427]: segfault at 0 ip 00007f11e20c747d sp 00007f11e0b43b00 error 6 in libxul.so[7f11e1dd9000+4c75000] [5251047.836429] Chrome_~dThread[11405]: segfault at 0 ip 00007f9e2dcc747d sp 00007f9e2c743b00 error 6 in libxul.so[7f9e2d9d9000+4c75000] I have run the script against the firefox-61.0.1.tar.bz2 linux64 tarball. It produces identical results. I have not been able to replicate this on current (20180709) nightly. If needed I can upload the dumped core file somewhere for further investigation.
I have tried the same test script with ff 62-beta8 and there are intermittent crashes. Update with latest nightly 20180801. The situation is even worse than 62-beta8 as almost all 5 threads are crashing on every test run! The logging in /var/log/messages is identical to before: [ 3398.379729] Chrome_~dThread[25633]: segfault at 0 ip 00007f0acf4c82cf sp 00007f0ae0638b00 error 6 in libxul.so[7f0acf19c000+526b000] [ 3398.463639] Chrome_~dThread[25314]: segfault at 0 ip 00007f13434c82cf sp 00007f13546ddb00 error 6 in libxul.so[7f134319c000+526b000] [ 3398.463854] Chrome_~dThread[25195]: segfault at 0 ip 00007f249e6c82cf sp 00007f24af8bab00 error 6 in libxul.so[7f249e39c000+526b000] [ 3398.463886] Chrome_~dThread[25643]: segfault at 0 ip 00007f9f132c82cf sp 00007f9f244cbb00 error 6 in libxul.so[7f9f12f9c000+526b000] [ 3399.365063] Chrome_~dThread[25770]: segfault at 0 ip 00007f1ce6dc82cf sp 00007f1cf7f9bb00 error 6 in libxul.so[7f1ce6a9c000+526b000]

Is this still an issue?

I think I recently started running into this on Firefox 114.0 built on Gentoo. Can't say for certain which version started causing the issue. Also, sadly, I can't reproduce it reliably. Let me know if this is the same issue, and if I can provide any other logs or build Firefox with more debugging options etc.

(In reply to Dave Townsend [:mossop] from comment #6)

Is this still an issue?

I think I recently started running into this on Firefox 114.0 built on Gentoo. Can't say for certain which version started causing the issue. Also, sadly, I can't reproduce it reliably. Let me know if this is the same issue, and if I can provide any other logs or build Firefox with more debugging options etc.

Given the information we have it's impossible to say. Please file a new bug if you can reproduce your issue with an official build.
