Couldn't get connection maximum connection count (5/5)
May 14, 2012
when i use VoltDB V2.6,I found this issue:
Couldn't get connection because we are at maximum connection count (5/5) and there are none available.

Can you help me?
Hi, The maximum connection
May 14, 2012

The maximum connection count is set based on the max number of file descriptors allowed per process. We use JNA to retrieve it. If you run `ulimit -a` what do you get? If that is set to something reasonable then there be a bug using JNA to fetch that value. What is the output of `uname -a`?
