hello all,

i'm having an unusual problem with mysql here in a bioinformatic
application. in these cases, the server "hangs" upon receiving a query. i
can't predict which queries will trigger the problem, but once one comes up,
even restarting the server doesn't keep it from happening. i also erased the
files in /var/lib/mysql/test/ suspecting that it had got into an
inconsistent state, but that didn't help either.

when the hang occurs, whether triggered from the monitor or my perl program,
the program sends a query via a socket to the daemon and waits for the
response. the server is stuck waiting on a select call. 

rebooting the machine seems to reset the criteria determining which queries
cause the system to fail, but something still does, and rather quickly. i'm
getting between 1 and a dozen queries done before one fails, and failures
occur on reruns at places that worked previously.

any suggestion is welcome; i'm really puzzled!

thanks,

aaron brick.
