1 . Out of memory
If PuTTY tries to allocate more memory that system has given it then “Out of memory” error get occurred. It may also takes place for genuine reason : if you have configured huge number of lines of scrollback in your terminal or if your machine really run out of memory. The PuTTY is not capable of handling such errors when system runs of memory and immediately it will terminate after giving “Out of memory” error message.
However, this error may also occurred when PuTTY receive data in wrong format. In SFTP and also in SSH-2, the server will send the size of each messages before itself, so that PuTTY will receive the size and try to allocate space for message, and then receive rest of the messages. If PuTTY receive garbage size then it automatically allocate a ridiculous amount of memory and will terminate by giving “Out of memory”.
