Status: RESOLVED FIXED

(Core :: General, enhancement)

Description

[Eliza Balazs [:ebalazs_]]

After some retriggers and backfill I found that the first failure started with this push
https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=0e62eb7804c00c0996a9bdde5350328a384fb7af&filter-resultStatus=testfailed&filter-resultStatus=busted&filter-resultStatus=exception&filter-resultStatus=runnable&filter-resultStatus=running&filter-resultStatus=pending&filter-resultStatus=success&selectedJob=158803228
and it became permafailing with this push:

From the logs it looks like the tests are passing, but they are taking too long. We should probably increase the timeout of the task or increase the number of chunks.

-----------------------------------------------------------------

lets do this- if we need to go to 12 that would be ok as well.
