This is a > regression and used to work fine in the 1.1 release. Note that the agent does > unregisters with the master and the crash happens after that. > Steps to reproduce: > - Start the agent. > - Send it a {{SIGUSR1}} signal. > The agent should crash with a stack trace similar to this: > {noformat} > I0209 16:19:46.210819 31977472 slave.cpp:851] Received SIGUSR1 signal from > user gmann; unregistering and shutting down > I0209 16:19:46.210960 31977472 slave.cpp:803] Agent terminating > *** Aborted at 1486685986 (unix time) try "date -d @1486685986" if you are > using GNU date *** > PC: @ 0x7fffbc4904fc _pthread_key_global_init > *** SIGSEGV (@0x38) received by PID 88894 (TID 0x7fffc50c83c0) stack trace: > *** > @ 0x7fffbc488bba _sigtramp > @ 0x7fe8a5d03f38 (unknown) > @ 0x10b6d67d9 > _ZZ11synchronizeINSt3__115recursive_mutexEE12SynchronizedIT_EPS3_ENKUlPS1_E_clES6_ > @ 0x10b6d67b8 > _ZZ11synchronizeINSt3__115recursive_mutexEE12SynchronizedIT_EPS3_ENUlPS1_E_8__invokeES6_ > @ 0x10b6d6889 Synchronized<>::Synchronized() > @ 0x10b6d678d Synchronized<>::Synchronized() > @ 0x10b6a708a synchronize<>() > @ 0x10e2f148d process::ProcessManager::wait() > @ 0x10e2e9a78 process::wait() > @ 0x10b30614f process::wait() > @ 0x10c9619dc > mesos::internal::slave::StatusUpdateManager::~StatusUpdateManager() > @ 0x10c961a55 > mesos::internal::slave::StatusUpdateManager::~StatusUpdateManager() > @ 0x10b1ab035 main > @ 0x7fffbc27b255 start > [1] 88894 segmentation fault bin/mesos-agent.sh —master=127.0.0.1:5050 > {noformat} -- This message was sent by Atlassian JIRA (v6.3.15#6346)
