[boinc_dev] [patch] mystery solved? Aw: Re: BOINC having too many open files - failure in opendir()
Dear all, I skimmed through all invocations of (boinc_)?fopen() in api/ and lib/, seeking the respective matching fclose(). What I found missing I placed here http://anonscm.debian.org/gitweb/?p=pkg-boinc/boinc.git;a=blob;f=debian/patches/fopen_closing.patch;hb=HEAD as a patch. The trickiest and possibly the most important one is the omission of a close in the destructor of the MFILE class. Cheers, Steffen Gesendet: Freitag, 17.

[boinc_dev] FW: BOINC logos
From: paddy...@live.co.uk To: boinc_dev@ssl.berkeley.edu Subject: BOINC logos Date: Sat, 18 May 2013 21:48:30 +0100 Hello Sir/Madam, I am contacting you to request permission to use the BOINC logo. I am a member of a forum and have been asked to design a badge system for various contributions, one being our own BOINC team, which I have incorporated the logo into. Obviously we don't want to run into any copyright issues, so would like to make contact beforehand to make sure that we have permission to do so? Any help on this matter would be greatly appreciated.

As far as I can tell, none of these changes would fix a file descriptor leak in the client. We need a system-call trace that shows open()s. It's also possible that the system is running out of file descriptors because of software other than BOINC. -- David On 18-May-2013 4:00 AM, Steffen Möller wrote: Dear all, I skimmed through all invocations of (boinc_)?fopen() in api/ and lib/, seeking the respective matching fclose().
