DR node Ping timeout

rendering irradiance map on DR with 2 Q6600 i’m experiencing this problem:
both pc partecipate to DR on frames #0 - 2, in the middle of 2 spawner buckets disappear and irrmap rendering uses only 1 pc.
so i try restarting manually slave spawner and this is what i get:

warning: Render host unknown (ip) is not responding
Render host (ip) added
Ping not received from host 0.0.0.0 for 610453 milliseconds, dropping connection.

any idea for? thanx for any reply

Check the vraylog.txt file on that machine, perhaps it can tell something useful.

Best regards,

hi vlado.
i had to reboot and decrease irradiance map size to solve, so vraylog has been cleared.
checking spawner log i found following:
