I don't think that I am using the non-NPTL version since I
installed FirebirdSS-1.5.2.4731-nptl.i686.rpm.

This is the first time that we got this kind of error since I
installed the above rpm several months ago.

When I noticed the error, I shutdowned JBoss that resulted in
error and rebooted it. But I did'nt shutdowned Firebird SS since
it was servicing other JBoss applications. However, rebooting JBoss
didn't solve the problem, we still got the same error.

Then, I shutdowned one of other JBoss's wandering that the error
might be caused by insufficient memory.
What happened then was that the error disappeared !!!
This phenomenon suggests that the error was caused insufficient
memory.

Can we avoid the error if we prepare enough size of memory?
