Intermittent ping problem
Posted on 2003-11-05
Heres the situation, to test a theory I made a simple batch file that ran ping about 50 times per minute. I let this file run overnight and log to a text file along with a time stamp (provided by time /t). This .bat file was run from a client machine (A) to a database server machine (D).
D= HP ProLiant running SQL 2000 SP3, and win2000 Sp3. It has dual Intel Nics running in a team using Hp's Teaming driver.
A= HP d325 (Athlon XP/512MB DDR/integrated 3Com 3c920B), Win2000 Sp3
At various times during the night the ping comes back with "Request timed out." Normally I wouldn't be so "anal" about this because it seems to occur in about 0.1% of the lines in the log, however machine A runs a program that communicates directly to the DB server and is VERY sensitive to any disconnect or downtime. One group of "Request timed out" was about 8 in a row (translating to about 10 seconds). During this time the program running on A crashed out.
Topography: Both machines (all 3 Nics) are plugged into the same Switch (Advance Stack 800T 8 port modular switch Model#: J3245A)
Can anyone think of any reasons why this could be happening? Changing the program on A is not an option. Trust me, I wish it were!
