As a result, many service checks take a long time to complete (4-5 minutes in some cases). To try and debug this I attached strace to several of them, and got very similar output every time. Here is a sample: write(7, "servername\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 504) = 504 ------------------ insert long pause here ---------------------------- close(7) = 0 _exit(0) = ? All of the processes that seem to take a long time to complete seem to be waiting on IO somewhere, since the write call takes quite a while to complete. I can't seem to figure out which file they are writing to here. Does anybody know? --Ben ============================================== Ben Nelson Sr. Systems Administrator, Hosting RightNow Technologies (www.rightnow.com) A Better Way to Serve Your Customers </BODY> </HTML>
