Too many simultaneous connections Gmail error

I use JETI plugin and I have this error

=====> atlassian-jira-incoming-mail.log <=====

2014-10-20 16:12:17,783 ERROR [] QuartzScheduler_Worker-0 ServiceRunner APT - Issues APT - Issues[10520]: Error connecting to host '' as user '' via protocol 'imaps': javax.mail.AuthenticationFailedException: [ALERT] Too many simultaneous connections. (Failure)

I have already seen that Gmail has a 15 connection limit on IMAP servers. Is there a way to solve this problem? And, case not, will i lose information or does JIRA retry creating tickets?

I have not seen this kind of problem with JETI so far, but I do believe it is not related to JETI.

IMAP email connections to email accounts are managed by JIRA not by JETI, as the stacktrace reflects it.

By default Mail Fetcher Service is connecting every minute for new emails. 

Is the connection to fast? Slow network or stuck connections may also cause this problem I think.


It may be enough to increase the period, the service is checking emails. Perhaps increasing it from 1 minute to 3 or 5 is enough.

You can increase this in JIRA Administration / Services / Mail Fetcher Service.

There is also a Delay parameter in the Mail Handler in Administration / Incoming Mails. You may wan to try to increase it as well.
