My shifts start out good and stay that way for a day or two then they start to drop off and become erratic. Should I be restarting the client or PC every so often? I did notice you have options to automate certain things in the Bitminter client, is that something I should be using?
A couple users have reported increased memory usage as days go by and eventually sluggish response from Bitminter client. I run it for weeks/months at a time and have been unable to reproduce this issue.
If you are having this issue, a java heapdump would be greatly appreciated. You'll need JDK (java development kit) installed for this.
