This is actually triggered by the TeamCity plugin, which makes it unusable because the deadlocks have significantly increased recently.

I haven't seen this any more, even with the TC plugin installed (but Maven is disabled). Maybe it's obsolete.

I don't know what happened in RC3 (or RC2), but the issue is now reproducibly back, on two different machines. That's a total show stopper.

Sascha,

Can you please create a list of all plugins you have installed?


[ Permlink | « Hide ]
Sascha Weinreuter - 08 Oct 07 14:05
Sure, here it is. Although I don't remember that I recently changed anything plugin-related, and some of them are also not present on my machine at home.
