Listener-Thread Error 25571

Today we saw hundreds of lines in our message log with the following error. The database pretty much came to a halt and nobody could connect or do any work. Only bouncing the engine cleared up this issue. 17:15:47 listener-thread: err = -25571: oserr = 0: errstr = : Cannotcreate a user thread. 17:15:48 listener-thread: err = -25571: oserr = 0: errstr = : Cannotcreate a user thread. 17:15:49 listener-thread: err = -25571: oserr = 0: errstr = : Cannotcreate a user thread. 17:15:50 listener-thread: err = -25571: oserr = 0: errstr = : Cannotcreate a user thread. Does anyone have any idea what this might be attributed to or what would have caused the issue? Any help would be great, --David in4mixdba@gmail.com

Are you using it? If yes, could it be that someone changed the group users? The other reasons mentioned in the finderr message for this error are lack of resources (it should give an OS error or you should have something in /var/adm/messges or /var/log/messages) and some GLS related stuff... Do any of these make sense in your system? Regards -- Fernando Nunes Portugal http://informix-technology.blogspot.com My email works... but I don't check it frequently...

Fernando, Thanx for your help. We are not using the $INFORMIXDIR/dbssodir/ seccfg Also, we did check the message/log files you pointed to and there was nothing there unusual.. Any other ideas? --David in4mixdba@gmail.com On Nov 13, 6:46 pm, Fernando Nunes <s...@onlinedomus.net> wrote: > Dave wrote: > > Today we saw hundreds of lines in our message log with the following > > error.
