Hi, I'm running proxy server from the master branch and I consistently get a dead lock after running jobs more than 15 min, e.g., http://uaf-2.t2.ucsd.edu/~alja/traffic.png The lock seems to be related to removing sockets in the client after elapsing the XRD_DATASERVERTTL of the proxy. This is what I inferred from debugging proxy with gdb (I picked a locked up thread and followed the owners of contended locks): https://gist.github.com/alja/2e6a69c48f864cccf1d9#file-xrdcl-pollerbuiltin-removesocket-bt-txt-L12 and server debug messages http://uaf-2.t2.ucsd.edu/~alja/proxy-lock.log If I set the TTL high enough the proxy server can be 100% efficient and stable. The lock is not simple to reproduce -- I'm running 600 jobs with 10% probability of replicated file paths. The gcore after lock-up is in noric38.slac.stanford.edu:/usr/work/matevz/gcore.12905 Thanks, Alya ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-DEV list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-DEV&A=1
