[SOLVED] pmg pmgproxy[489]: Deep recursion on subroutine

[slava_ua]

Good day!

Recently, such zaps have begun to appear with a certain periodicity:


Jun 04 09:54:41 pmg pmgproxy [489]: Deep recursion on subroutine "HTML :: Element :: delete" at /usr/share/perl5/HTML/Element.pm line 567.

Do not mention it ?

P.S. Mail Gateway version 6.4-4

When does this happen?
Could you try correlating the log-message with requests made to pmgproxy (/var/log/pmgproxy/pmgproxy.log)?

 

[slava_ua]

Yes, I delivered a log in the interval when there was a message

 

[Stoiko Ivanov]

Thanks - hm - the most likely calls that might cause this (without verifying in the source-code's dependencies) - are the ones
that display quarantined mail - my guess is that one of the mails in the quarantine has content that causes the bug - it would be interesting to get
its content and try to reproduce it - the most likely quarantine IDs are:

C0R2160T94353506
C0R2159T133318405

You can see the IDs in the brower's developer tools (network tab) if you click on a mail in the quarantine.

Yes, indeed, there is a letter with a prohibited file type in the attachment quarantine, the content of the file may be bad
