A user told us on the mailing list that he got a crash. It was SIGXFSZ, File size limit exceeded… Due to the protocol log file growing too much, probably 2 or 4 gigabytes…
The end of his log reads:
IMAP4< 8918737 OK Status completed.
The number at the left is the transaction id of the IMAP protocol, incremented by 1 on every command. That means almost 9 millions commands :-) Our user started Claws Mail on March 10, it crashed on April 17 only due to the log file.
Comforting to read that :-)
