Hi all, I'm facing a strange issue. I have a major performance penalty on some apache related operations (svn checkout that used to take 5mn but that suddenly takes more than 7 hours). I'm running a standard RHEL5.3 with apache 2.2.3 (fyi the server runs mod_php, mod_auth_mysql and some other modules too). Thanks to strace, I identified that the httpd process that is "very long" (the httpd process that discuss with svn client that takes hour to complete). The process makes a lot of operation on a file descriptor attached to my ldap server and is regulary blocking with following syscall: poll([{fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 1, -1 <unfinished ...> fd3 is a socket (/proc/<pid>/fd/3) and the inode of this socket is used to communicate with the ldap server (shown by netstat) This is where I no longer understand what happens: - I'm using mod_ldap so there should be a cache of all ldap info. - ldap-status confirm that the credentials used for the svn operation are in cache. - The cache is far from full (2%) - The hit ratio is close to 100% => Why there is an activity between my httpd process and the ldap server ? Any help appreciate, Cheers, Manuel --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
