deadlock on setprice

[cipig]

mm2 from mm2.1 branch runs into a deadlock on setprice requests after running for a day. When it happens, i have to kill mm2 and restart. There is no load or CPU usage.

logfile:
mm.log.txt

deadlock does not happen on dev branch
the logfile is from a node that has this many orders/updates:

one of my nodes ran into this deadlock just now (mm2.1 branch)... i can still query orderbook, but setprice calls are not working any more, they simply don't return and also don't timeout (eg curl --url "http://127.0.0.1:7783" --data "{\"userpass\":\"$userpass\",\"method\":\"setprice\",\"base\":\"NAV-BEP20\",\"rel\":\"NAV\",\"price\":1.02,\"max\":true,\"min_volume\":30}") does simply nothing
same with my_orders, it get's stuck
but my_balance is still working

it is the same node as above, with the same number of orders, last output on seed node looks the same (orders_uuids=1371):

logfile of that node:
mm.log

strange thing about this is that it didn't happen a couple days ago and i have not increased the number of orders, i actually decreased it by lowering the number of base coins from 10 to 8 on all nodes

closing because it doesn't happen on dev branch... running for a long time on many nodes, including GUI
