Attached corrupted cache |

Hi Dmitrii. I don't think we can just limit all messages to 32MB. Lots of CFX users have messages that exceed this size. Why do you believe the large message corrupted the cache? Is there a repeatable re-create procedure to make this happen? |

I've noticed that at application start memory consumption jumped to 1.7GB
Reason is corrupted cache file in %LocalAppData%\Temp
which lead to invalid number of bytes to be read from file in CFXEnvelope.ReadRecord
BinaryReader.ReadBytes(len) always create buffer byte array with requested len.
Proposal is to limit maximum allowed CFXMessage size to 32MB
In case message in BinaryReader is bigger - invalidate cache.
