Re: Warning: Got signal 14 from thread X

Alex,

I looked at the new debug log you sent and obviously some client is
making connections to your server. This cannot come from
Innobase, there must be some client process running on your machine.

From the debug log I find the following:
...............................
T@11   : info: handle_one_connection called by thread 1
T@11   : info: check_connections called by thread 1

...<snip>........

T@11   : >vio_read
T@11   : | enter: sd=10, buf=5a48230, size=4
T@11   : | error: Got error 11 during read
T@11   : | exit: -1
T@11   : <vio_read
T@11   : info: vio_read returned -1,  errno: 11
T@11   : >thr_alarm
T@11   : | enter: thread: T@11  sec: 5
T@11   : | info: reschedule
T@11   : <thr_alarm
T@11   : >vio_is_blocking
T@10   : | >process_alarm
T@10   : | | info: sig: 14 active alarms: 1
T@11   : | exit: 0
...............................

Obviously vio_read fails on an error 11, and then mysqld calls
thr_alarm to produce signal 14.

From /usr/include/sys/errno.h I find:

#define EAGAIN  11      /* Resource temporarily unavailable     */

Probably Sinisa can find out what is the problem here.

Regards,
