I'm setting up an HA ftp server (amongst other services). When two connections happen simultaneously, and (more specifically) the same user from two IP's attempt to access the same file (one for reading, and one for writing), the processes both hang. And all subsequent attempts to either read or write the file fail. The two processes that seem to have caused the lock: user 24139 1657 Thu Apr 1 18:25:01 2010 proftpd: cbs - ::ffff:xxx.yyy.0.253: RETR prim_wo_img_dom.obs user 24142 1657 Thu Apr 1 18:25:01 2010 proftpd: cbs - ::ffff:xxx.yyy.103.208: STOR prim_wo_img_dom.obs (there are 49 other process trying to do the same things, but these are the first ones.) I'm more than happy to provide any information needed on this issue: OSL CentOS release 5.4 (Final) uname -a: Linux prtftp01<omitted> 2.6.18-164.11.1.el5 #1 SMP Wed Jan 20 07:32:21 EST 2010 x86_64 x86_64 x86_64 GNU/Linux ocfs2 version 1.4.4 At the moment, only one host is actively serving FTP at any time. I can fail the services back and forth as needed. --Jason -------------- next part -------------- An HTML attachment was scrubbed...
