I am getting a steady amount of select errors on my long-ish micro lan.
I edited the owfs code to determine which select error i was actually
getting, it seems i am getting a lot of BUS_transaction_nolock errors on the
main branch of each of my couplers. No errors report on the aux branch
strangely.
Feb 14 22:33:07 ubuntu OWFS[17145]: CONNECT:
ow_select.c:BUS_select_subbranch(193) Select subbranch error
//BUS_transaction_nolock// on bus 2:2 coupler 1F D6 65 05 00 00 00 8D
subbranch main
I have 4 couplers that i am switching for various sensors beyond them.
A graph of the stats is here it's fairly constant:

So my question is, if i am not seeing any other type of error, what should i
be looking for to clean up these select errors?
Thank you.

My changes to owfs-2.8p6/module/owlib/src/c/ow_select.c for those
interested.
