awgtpman issues

Jenne, Dave, Jim:

we experienced some TP issues this morning. Command line "diag -l" was slow to start and did not support testpoints. First we restarted the models on h1susauxh34 since this showed errors over the break and had CRC errors, this did not fix the TPs. Next we restarted the awgtpman process on h1asc and this did fix the problems. Remember that h1asc has a special awgtpman process to permit more testponts to be opened. The reason for today's problem is unknown.

Guardian reboot

Dave, Jim:

To ensure the python leap-second updates were installed on all nodes, we rebooted h1guardian0 (it had been running for 33 days). All nodes came back with no problems. We recovered about 4GB of memory.

python gpstime leapseconds

gpstime package updated, see alog 32919 for details.
