Hi Daniel,

I have sent the messages over to you.

I look forward to hear what you can find.

Best,

Charles

Hello,

the content of ps->param is pretty much all invalid. So looks like a callback on a freed/invalid parameter, could be a double-callback execution.

Set debug=3 and send all the messages for such case -- it might be quite a lot of them, so send them to my email address, the mailing list has a limit of message size.

Cheers, Daniel

Yes, it is a test server so very happy to arrange for remote access if required. In the meantime, I will do a little more digging to try to find out why entity is null.
