HELP es40 simple_lock: time limit exceed.

Last Decemember, I upgrade my ES40 from one 677Mhz CPU, 1GB Memory to two 833Mhz CPU, 2GB Memory. My ES40 had crashed for 13 times.

I got messages from /var/adm/messages as follows:

Re: HELP es40 simple_lock: time limit exceed.

Unfortunately this could be both hardware and software as you changed multiple things at once. Your version of Tru64 UNIX is quite old. Could you upgrade?

Can you see if it's always the same CPU and/or always the same lock? That knowledge might point you in the right direction. For instance if it's a hardware problem, then one possibility is that the CPU holding the lock is hung. Note that the CPU crashing the system, is not the one that would be hung.

Re: HELP es40 simple_lock: time limit exceed.

I am not sure, but I think that simple_lock problem was fixed in PK4 for 5.1.
Upgrade to 5.1B would be nice, but it would help only if the problem was software related.
As Han said, can you give more informations about what CPU crashed the system?
Did you upgrade the firmware after instalation of new CPUs?

Thanks to Mr. Han and Vladimir.
I checked the session logs in /var/adm/patch/log, the patch 1163.00 in PK6 was not patched, because the sys_check have some problem. the sys_check version is 1.34. I'd like to delete the sys_check134, and reinstall the PK6 then install sys_check 1.4

Re: HELP es40 simple_lock: time limit exceed.

I repatched the PK5, It seems OK. The ES40 look like no problem. I decide to close this thread. Thanks to everyone who help me.
