#51pushing too many/too large patches at once can fail and leave a stray lock
Related to #46.
With a "too large" push, all memory on the server can be consumed, triggering the OOM killer which kills one or more related processes leaving stray processes and their lock file, or just a stray lock file. OOM kills can be seen in kern.log and syslog. amgarching has a test repo which seems to reproduce this.
- summary changed to "pushing too many/too large patches at once can fail and leave a stray lock"
i have the suspicion i hit the same issue, but please have a look at it.

oh, is it markdown?

same problem w the stock 2.5 osx version:
$ darcs-2.5-OSX-10.6-i386 push onetom@hub.darcs.net:test Note: if you want to change the default remote repository to onetom@hub.darcs.net:test, quit now and issue the same command with the --set-default flag.

BUT it worked with the ubuntu 12.04 LTS version, which is 2.7.99.1 (release candidate 1)
testThe original issue is probably independent from mine and still valid.
My problem was the lack of support for the Control Master SSH feature. If I turned that off, everything worked perfectly.
