Sorry, up to know I haven't known ulimit -a
here are all values:
core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 4096 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) unlimited cpu time (seconds, -t) unlimited max user processes (-u) 7168 virtual memory (kbytes, -v) unlimited

Have you checked the ulimits for the user that's actually running the application that connects? You might just be running this application as root and running out of file descriptors...

Hello all!
Does anybody use DB2Connect on United Linux 1.0 We have the following Problem:
The DB2Connect Software enables access from DB2 Clients (e.g. for connecting Application Servers to Databases) to to DB2 Databases on Z/oS Systems. You can say that DB2Connect works as a gateway.
At the moment we can't open more then 1100 parallel connections per DB2Connect installation. But doing the same on AIX 4000 - 5000 connections are possible at the same time. At the moment, suing United Linux 1.0 reach 1100 Connections then the whole machine hangs and must be rebooted. We don't achieve the CPU and RAM limits.
Are there e.g. any kernel parameters that limit the number of parallel calls to a Server ?? We are using kernel 2.4.21! First of all, we get a sempahore error, but after changing the values in sysctl.conf, the were no further errors.
Is it possible, that Linux can't handle more then 1000 parallel connections? I don't hope so.
Thanks for answering!
