Crash on 4.05 Operating system call pthread_mutex_lock failed. Error code 22

[gerdus]

Error in log file:

Operating system call pthread_mutex_lock failed. Error code 22

Version: V4.0.5.3140 (from website)
OS: Linux
Mode: Super

Happened at startup of my application where it connects to about 50 databases in batches of 5 at a time.

I think this might be different issue than my other bug report (#8279) because the error in log file does not mention the lockmanager although undoubtedly related.
