I have some issues with cgminer client (https://github.com/dmaxl/cgminer) and the last p2pool release. The cgminer open sockets with p2pool until cgminer crashes after 3 to 4 hours. I have to restart my cgminer automatically to clean the sockets opened.
At the same time my Litecoind on the P2pool server return a lot of "VerifySignature failed: Non-canonical signature: S value is unnecessarily high" errors when cgminer is mining. Deleting the database didn't fix the error.

Very strange ... My platform worked correctly until I update all the softwares (p2pool / cgminer and litecoind).
Any idea how to correct this issue ? Is-it a bad management of the Litecoind errors from cgminer ?
