Jacques Le Roux commented on OFBIZ-2315:
----------------------------------------
Thanks for the update Philippe,
I have no time in a predictable future to look seriously at the other issues.
But I have not forgotten since I have a client who has also some issues of that
kind (thoug not with the trunk but something near R4.0 where I have already
switched from Minerva to DBCP)
My client told me that this issues could be related to orders with a lot of
lines (up to thousands) and at least 25 people creating such orders
concurrently in backend (not at a high speed though, like with an heavily used
eCommerce frontend, since there are a lot of item to put and lines to create in
each order)
He also told me that maybe async jobs could be involved (orders confirmations).
But this client does not use an SMTP server, so maybe simply avoiding to send
orders confirmations will solve his issues (crossing fingers ;))
