Re: [Condor-users] Condor SOAP hanging schedd.

Mailing List Archives Public Access	UW Madison Computer Sciences Department Computer Systems Lab

I've been having some trouble with condor soap queries hanging my

schedd. I have Condor 7.5.2 installed, with a pool of about 200

workers, and about 10000 jobs in my queue, and every ten minutes or

so, a script of mine is querying the schedd with the soap interface.

Normally, this takes about two minutes, and looks like this in the log:

06/16/10 10:39:51 Received HTTP POST connection from <127.0.0.1:59318>

06/16/10 10:39:51 Current Socket bufsize=85k

06/16/10 10:39:51 Current Socket bufsize=49k

06/16/10 10:39:51 About to serve HTTP request...

06/16/10 10:39:51 SOAP entered getJobAds(), transaction: 0

06/16/10 10:39:53 SOAP leaving getJobAds() result=0

06/16/10 10:41:20 Completed servicing HTTP request

However, I'll occasionally see the schedd get stuck, and not do

anything until I send it SIGKILL. The log looks like this:

[root@canfarpool ~]# tail /var/log/condor/SchedLog

As you can see, it's been stuck for about 40 minutes.

Has anyone else run into this?
