Description of the bug:

Since upgrading to 7.4.0 and subsequently 7.4.1 we've been hit by a server crash during random CI (and local) builds:

Server terminated abruptly (error code: 14, error message: 'Socket closed', log file: '/private/var/tmp/_bazel_build/a50428ec9d717925b6582741c513dab3/server/jvm.out')

Which category does this issue belong to?

No response

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

I have not found a way to reliably reproduce this issue but were seeing about 1-3 of these per day on our ~300 machine CI fleet.

Which operating system are you running Bazel on?

macOS

What is the output of bazel info release?

7.4.1

If bazel info release returns development version or (@non-git), tell us how you built Bazel.

No response

What's the output of git remote get-url origin; git rev-parse HEAD ?

No response

If this is a regression, please try to identify the Bazel commit where the bug was introduced with bazelisk --bisect.

No response

Have you found anything relevant by searching the web?

There was a GC threading issue in 7.4.0 that was also causing a server crash but that was fixed in 7.4.1 so this might be another case of that issue or something new entirely. I do not see any

Any other information, logs, or outputs that you want to share?

Attached are the Bazel server JVM log from the build it terminated on along with the .ips file generated from the crash.
