Hi,
At least one of our data servers is running into issues with load.
The data server is started with the
xrd.sched mint 8 maxt 25 avlt 4
In the xrootd log I am seeing entries like:
110325 19:11:34 25864 XrootdXeq: xroot.18727:63@gk03 login
110325 19:11:38 25864 ofs_stat: xroot.18727:80@gk03 Unable to locate /xrd/datadisk/step09/ESD/SWT2_CPB_DATADISK; No such file or directory
110325 19:11:38 25864 XrdLink: Unable to send to xroot.18727:80@gk03; broken pipe
110325 19:11:38 25864 XrootdXeq: xroot.18727:80@gk03 disc 0:01:12 (send failure)
I am wondering what can be/should be done about the broken pipe/send failures. What are these?
Since the data server is getting swamped, I am also seeing:
110325 19:11:59 25864 XrdScheduler: Thread limit has been reached!
I am interested in learning what is the best way to diagnose the problem to determine what to change on the system.
Regards,
Patrick
