Re: [MonetDB-users] Crashing server

Hi Ed, just a short question: How much diskspace do you have left on the partition where your dbfarm is located? It would be great to know the free diskspace both just before the and just after the server crashes. Thanks in advance, Stefan

Greetings!

Having some problems with the MonetDB server crashing.

- Start a server

- Have a client perform a lot of operations (_lots_ of BATs creation, bun insertions, etc).

- Every 10,000 or so operations, perform a on the client. Total operations: approximately 7500 BATs, 17,000,000 BUNs.

- Do an on the server to confirm all tables are clean.

- Now perform an on the server with every table clean.

MonetDB>abort(); #GDKmmap(6553600) fail => BBPtrim(enter) usage[mem=736705664,vm=2137835808] # !mallinfo.arena = 35753984 !mallinfo.ordblks = 4454 !mallinfo.smblks = 0 !mallinfo.hblkhd = 122863616 !mallinfo.hblks = 33 !mallinfo.usmblks = 0 !mallinfo.fsmblks = 0 !mallinfo.uordblks = 15990816 !mallinfo.fordblks = 19763168 #GDKmmap(6553600) fail => BBPtrim(ready) usage[mem=736705664,vm=2137835808] # !mallinfo.arena = 35753984 ... (and so on)

Doing a shows: core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) 32 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 14336 virtual memory (kbytes, -v) unlimited

Anybody have any ideas on why the server died? If I do it with less (_much_ less) operations, it at least succeeds (even though there is a lot of I/O occurring).

Regards! Ed
