I don't understand why the signature was replaced with an IPC error like that — the stack looks like graphics trying and failing to allocate memory internally, and I don't see any references to IPC anywhere else in the crash report (except MessageLoop, which isn't specific to actual IPC as I understand it).

If I had to guess the cause I'd assume address space exhaustion (32-bit build, large image, “NtAllocateVirtualMemory”), which might also be connected to problems with allocating space to map shared memory.

I hit this crash when trying to take a page screenshot of https://protosaur.dev/fission-experiment-monitoring-dashboard/dashboard/dashboard.html.

I think I know what's going on here: it's a paired minidump. (The only indication of this seems to be the additional_minidumps key in the Crash Annotations tab, which is… not great UI.) Specifically: the parent process fails to deserialize a SHMEM_CREATED_MESSAGE, sets the annotation, then interrupts the child process in the middle of some random other thing to kill it and create a crash report of that unhelpful state. I assume there's a corresponding parent process crash report buried in the DB somewhere, but that's also not very helpful, because I can probably tell you the stack just by looking at the source; it won't even tell me where in deserialization it failed.

That said, we will “fail to deserialize” a ShmemCreated if we fail to map the memory. So, despite working from bad data in comment #1, I ended up in roughly the right place: this is mostly likely due to address space exhaustion.

I hit this content crash again in Nightly 106. I crashed twice when trying to load a Google Doc. Probably an OOM since I have many Google Docs open and I'm running 32-bit Firefox.

Since the crash volume is low (less than 5 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.

Closing because no crashes reported for 12 weeks.
