Hi all! I have a problem with CentOS 4.4 and Communigate Pro 5.0.9. As our user number grows, we are seeing "too many files open" error messages in Communigate logs. I spoke with Communigate tech support and they asked me to increase the number of file descriptors which i did. I put 128000 as a script i made to check Communigate open files reported as high as 99000. As i checked the Communigate log file, it reported that it "sees" 1024 "available" file descriptors. Reporting that to Communigate tech support, the guy answered: "CommuniGate gets this number via getdtablesize() system call. Probably in CentOS the table has a fixed size so you need to recompile the kernel to expand it. Try upgrading CentOS to 4.5 (or whatever later version is available) " I'm a little afraid of upgrading the server right away, i don't want to worsen the problem. Or maybe it's safe to do it. I dunno. Is there anybody on the list that can comment on what the Communigate tech support guy said about the "getdtablesize" thing ? Thanks in advance! Guy Boisvert
