Hello!
Few times ago there was discussion about dxr3 + vdr. It seems to be unstable for pretty many user. I promised then to log the system and tell you what there happens.
My current setup:
Pentium II 400MHz, 256Mt, 20Gb VDR 1.3.23 + vdr-dxr3-0.2.3-cvs20050501 + dxr -driver from Skytta's old archive
Usually VDR works fine. Few times a day it freeze and I need to boot it. Symptoms are that picture freezes and sound cuts off. At the same time there is following information at /var/log/syslog:
May 9 06:41:50 vdr vdr[3062]: buffer usage: 70% (tid=98311) May 9 06:41:51 vdr vdr[3062]: buffer usage: 80% (tid=98311) May 9 06:41:52 vdr vdr[3062]: buffer usage: 90% (tid=98311) May 9 06:41:53 vdr vdr[3062]: buffer usage: 100% (tid=98311) May 9 06:41:53 vdr vdr[3062]: ERROR: 1 ring buffer overflow (177 bytes dropped) May 9 06:41:59 vdr vdr[3062]: ERROR: 6294 ring buffer overflows (1183272 bytes dropped) May 9 06:42:05 vdr vdr[3062]: ERROR: 7059 ring buffer overflows (1327092 bytes dropped) May 9 06:42:11 vdr vdr[3062]: ERROR: 7574 ring buffer overflows (1423912 bytes dropped) May 9 06:42:17 vdr vdr[3062]: ERROR: 7100 ring buffer overflows (1334800 bytes dropped) May 9 06:42:23 vdr vdr[3062]: ERROR: 7088 ring buffer overflows (1332544 bytes dropped) May 9 06:42:29 vdr vdr[3062]: ERROR: 7140 ring buffer overflows (1342320 bytes dropped) May 9 06:42:35 vdr vdr[3062]: ERROR: 7700 ring buffer overflows (1447600 bytes dropped) May 9 06:42:41 vdr vdr[3062]: ERROR: 7068 ring buffer overflows (1328784 bytes dropped)
so time later:

and more later:

System seems to be up as I can get connected to it with SSH. Sometimes it helps when I simply kill vdr and restart it but sometimes computer needs to be restarted.
I assume that system is up again at 08:44 when vdr is clearing transfer buffer.
I hope this information gives so information to coders who try to make system more stable. If you have anyidea what I can do, please let me / us know.
