about "Image error: out of memory"

Dear Bob,

I am a user of the program of ACP. However, recently, it can show up the error of "Image error: out of memory" sometimes. I don't know whether other users have met the similar situation, and I don't know how to deal with it either.

I have already tried the ACP version of 8.0, 8.1, together the MDL version from 5.21 to 6.08, but it seemed that all of these cannot help. This error raises up irregularly, and always shows up from time to time after running half of the whole night. Personally, I think it is the problem of memory overflow when the shoot ends while the MDL is making the preview picture.

Could you tell me how to avoid this kind of error? And the log documents are as following.

Thanks a lot.

We are having trouble identifying you. We can only find a "Nick" Yang with a PinPoint license but no one named Yang with an ACP license. I see you were given a non-customer login back in May 2018. The trial period is long expired. Can you help us identify you?

This is the post I posted for my teacher. For some reason he couldn't log on this BBS. His name is"Xing Gao"

Hello -- OK I found the license for Xing Gao. He gave us an email address of webmaster@xjltp.com but our system will not accept such addresses ("webmaster') for contact person. We tried to contact him at another address "jose*******tung@gmal.com but no one responded. Also the support contract for that license ran out almost 3 years ago. This is why you cannot see the support sections here.

I can try to help you once. Please stay on 8.1. This "occasional" error may be related to MaxIm DL. Considerable work has been done on MaxIm DL between 6.08 and 6.19. You may try turning off the "camera in separate thread" in MaxIm DL. I searched and found two discussions on this "out of memory" from 2015 and both were using MaxIm 6.08. You can't see these threads because your support is expired. My suggestion: First upgrade to MaxIm DL 6.19. That may solve the problem.

thank you very much！
