Reply to Fail to manage properly the Free Memory on Sipy on Sat, 04 Apr 2020 16:35:35 GMT

Good Day All,
I've developed several python scripts around pytrack, one of it expecting to log the tracked GPS position. I'm using several _thread for this, however, i'm having some memory problems...
In some circumstances it works, reload the Sipy.. and then suddenly a memory error occurs.. (even sometimes without modifying any scripts) - see below.
I do understand the free memory information is not the only parameter to take into account, rather the max blk & free sz... however, i do not find a way to manage it properly...
There must be something i'm doing wrong.. but... did not find it..
Thanks for your kind help
Regards
Patrick
