UUCP can't handle 19 concurrent connections?
First of all:
1. Yes, I have to use UUCP.
2. No, there is no way to replace it with RSYNC/SCP/etc.
3. Please don't tell me how to replace UUCP or why I should do this or why I shouldn't be using UUCP.
So here is a problem.
It looks like UUCP can't handle more than X (15?) number of concurrent connections over long (more than 10 min) period of time.
I've run lots of stress test (UUCP over SSH, plain UUCP) and it looks like I'm getting error PIPE BROKEN/ Time Out. I have 19 branches, 1 head office server, all connections are coming at the same time from the branches to the HO server. And every so often 1-2 would drop so I have to re-run uucico for that systems.
No, running 19 connections with scp doesn't fail so I'm assuming that network is fine.
I'm using Taylor's UUCP on RHEL4 with protocol "e". I'm suspecting that one of the buffers is overfilling somewhere within UUCP, but don't know how to check it/prove my theory.
Did anyone had similar problems? Is it a know issue? I've used google to research topic but can't see people mentioning this kind of problems.
All advice much appreciated. Especially how to see what's closing socket? No problems with ram (18GB, lots of free, swap not even touched!), no problems with disk speeds, no problems with CPUS.
Thanks in advance!
