I updated my server to 1.11.0.6826 and now get server freezes caused by dbi.mysql.ext.so
each freez makes the watchdog kill the server (SIGABRT).
In the crasstack I see that main thread gets stuck in vio_read_buff (possibly infinite loop in my_real_read?):
1 dbi.mysql.ext.so + 0x6535f int vio_read_buff(int a1, void *a2, unsigned int a3)
2 dbi.mysql.ext.so + 0x550eb unsigned int my_real_read(_DWORD *a1, unsigned int *a2)
3 dbi.mysql.ext.so + 0x5550f int my_net_read(int a1)
4 dbi.mysql.ext.so + 0x50e4f signed int cli_safe_read(int a1)
5 dbi.mysql.ext.so + 0x5156f signed int cli_read_query_result(int a1)
Not sure if it is related to the new version, I've got 2 such crashes so far.
