HPUX system crashing at multi-user boot - single user mode boot ok...

HPUX system crashing at multi-user boot - single user mode boot ok...

I have an HP-UX system that's crashing when coming up in multi-user mode.  When it boots in single-user mode, it comes up ok.

 

It objects to a kernel module prior to the crash, then crashes with a "panic: kalloc: out of kernel virtual space" error.

The physical memory in the system hasn't changed.

 

Any ideas please?

What version of HP-UX are you running?  What model of system is this?

I believe it's 11.11 and it's on an rp3440.

If you have a support contract have a look at this:

https://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?spf_p.tpst=kbDocDisplay&spf_p.prp_kbDocDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c01096262-3%257CdocLocale%253Den%257CcalledBy%253DSearch_Result&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken

 

For this particular issue apparently a couple of the semaphore kernel parameters were too large.  

 

"To resolve this issue, we decreased semmnu and semume to half of their value."

perhaps it would be good to ask what changed?  was the kernel recently modified?  were kernel parms changed?  was software added?

I agree Donna - that's my first port of call.  Unfortunately, I don't know the answer I'm afraid.
