> matching regex 'Detected pause in JVM or host machine', but found 0 lines.
> Last line was:

> died: write() send(): Broken pipe
> {quote}
> The actual log (archived later) contains:

> I0211 18:34:03.563254 2392 thrift-util.cc:113] TAcceptQueueServer client
> died: write() send(): Broken pipe
> I0211 18:34:03.565459 2164 JvmPauseMonitor.java:187] Detected pause in JVM
> or host machine (eg GC): pause of approximately 4550ms
> No GCs detected
> {quote}
> so if test_jvm_pause_monitor_logs_entries had waited for 3ms more it would
> have seen the line it was looking for (assuming the simplest explanation).
