Re: [Condor-devel] ProcAPI Messages

Hello All,
I set RESTART_PROCD_ON_ERROR to false and then started up the daemons again. It confirmed my suspicions that the schedd was still not happy. Actually it seems that it is something called condor_procd that seems to be the one that is having trouble. The SchedLog has the following: 
===

I am not sure what the issue at hand could be?

Ideas or suggestions greatly appreciated.

Thanks

Hello All,
Still working on getting 7.2.2 to fly on an OSx Leopard. After hacking the age, creation_time and sample_time variables use an unsigned long type, things seemed to get better, but still no joy. Then using Peter's suggestion of upping the maxprocs that helped things a lot, but alas, still no joy.
Now the condor_master, schedd, startd are all running but no job submissions will run. It seems that schedd is generating tons of log and consuming anywhere from 18-25% of the cpu as reported by top.
I found an OSX crash report message for condor_procd in /var/log/system.log. Here is the contents of the crash report:

It is beyond my comprehension, but I thought it may help.
I am going to find the code contribution agreement and get that submitted also. Although at this point I am not confident that the unsigned long was the right thing to do. 

TIA

Hello All,
I modified the procapi.h file so that all of the age, creation_tim and sample_time variables use an unsigned long type. That seems to have fixed the ProcAPI errors that we were seeing. 

But now we are seeing the following in SchedLog:

I am not sure what to do at this point?

Ideas / Suggestions?

Do you have your process limit set really low for your uid?

As for the code changes, you could attach a patch to you message
and we can see if we can apply it. I'll have to scrutinize the patch
closely because even though one might think the age of a process can't
be negative, due to kernel issues a negative age actually could be
calculated, so I'd need to do some inspection.

Have you signed our code contribution agreement?

Thank you.
