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.

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
