This is the section that determines the number of WU's SetiQ will cache:
# min_limit limits the minimum queue threshold.
# max_limit limits the maxumum queue threshold. These are used if
# for some reason the queuing app is downloading too many work units.
# This allows an override to reduce the numbers.
min_limit=3
#max_limit=20
# This setting will increase the upper limit of the queue size
# to be at least 'max'. The maximum value for this setting is 200.
max=10
Set min_limit to the absolute minimum you want SetiQ to allow before it will connect and max_limit to the absolute maximum SetiQ will EVER cache.
Then, set the max= to 40, and SetiQ will set the 'Maximum Queue' to be at least 40. (If your daily average would cause you to need 50, then the max will be raised to 50, but it will always be at least 40, no matter how low your average is.) The example I quoted here is for a 'loner' machine that averages about 3 WU's a day, so setting the max=10 line makes sure I always have at least 3 days worth stored, even if I get several long WU's that lower my average WU time, and would then normally lower the # of units in the cache.
That's probably more than you wanted, but I thought I'd try and be thorough, just in case you had any other questions.. 😉
