Your hostsâ€™s quota has been reduced because of the erroneous results it submitted. Donâ€™t worry; each successful result returned will double the quota until itâ€™s back up to the default level. A typical result shows [â€¦] Can't create shared memory: system shmget [â€¦] The only change I have made to my system was about 2 days ago when I started running the Mac beta Climateprediction.net boinc module. Before I had no problem. Related? Slightly. In brief, Appleâ€™s default system configuration is stingy with shared memory, even on multiple-CPU systems that are shipped with ample RAM. BOINC needs a separate block of shared memory for exchanging data between the client and each instance of a science app (one for each folder in the slots directory). Adding another project probably pushed you over the limit. For a more detailed discussionâ€”and a remedyâ€”see Configuring Shared Memory on Mac OS X from the Pirates@home website. ____________
