I think on previous mailing list I pasted the whole content. So I am again sending my reply in sort of confined way. :)
Eliezer, I am running on amazon linux 2 ami which I suppose is based oncentos.
I ran the uname -a command and this is what I get;;
Linux ip-172-24-9-143.us-east-2.compute.internal
4.14.256-197.484.amzn2.x86_64 #1 SMP Tue Nov 30 00:17:50 UTC 2021 x86_64

[ec2-user@ip-172-24-9-143 ~]$ openssl version
OpenSSL 1.0.2k-fips 26 Jan 2017
thanks so much and let me know the script and I can run on this machine.
Usama

Hey Usama,
There are more missing details on the system.
If you provide the OS and squid details I might be able to provide a script that will pull most of the relevant details on the system.
I don?t know about this specific issue yet and it seems like there is a SSL related issue and it might not be even related to Squid.
(@Alex Or @Chrisots might know better then me)
All The Bests,

Subject: Getting SSL Connection Errors
Hi I have a squid running on a linux box ( about 16GB ram and 4 cpu ) -- it runs fine for the most part but when I am launching multiple jobs that are connecting with salesforce BulkAPI, sometimes connections are dropped. its not predictable and happens only when there is so much load on squid. Can anyone shed some light on this? what can I do? is it a file descriptor issue?
I see only these error messages from the cache logs
```
PeerConnector.cc(639) handleNegotiateError: Error (error:04091068:rsa routines:INT_RSA_VERIFY:bad signature) but, hold write on SSL connection on FD 109
```
