[ceph-users] Re: Problems with ragosgw

Hi Mohamed, I’m not too familiar with the Raspberry Pi platform or Raspbian. But there are some clues in the output you provided, specifically this text — “ Thread::try_create(): pthread_create failed with error 11”. I assume these low valued error codes are consistent between Fedora and Raspbian, and so the code 11 means: #define EAGAIN 11 /* Try again */ I found the following: https://stackoverflow.com/questions/47078106/pthread-create-fails-with-eaga… <https://stackoverflow.com/questions/47078106/pthread-create-fails-with-eagain> So that seems to leave 3 possibilities: 1. RGW is asking for more resources that your platform is able to provide. a. There are limits as to the number of threads. b. There may be a memory limit, since each thread needs to maintain its own stack. 2. There is a bug in RGW where completed threads are not thread_join’d by their parents. a. This seems unlikely as this appears to happen during start-up before threads are likely done with their work. 3. Florian Weimer identifies a kernel bug. I suspect it’s #1, so you might want to try reducing the number of threads rgw uses by lowering the value of rgw_thread_pool_size in your configuration. Eric -- J.
