SYMPTOMS
If the IMS receives an inbound SMTP message that includes a large number of consecutive carriage-return line-feed (CRLF) characters in Japanese encoding, the message may be truncated at the CRLF characters, or the Information Store may stop responding. If the message is very large, stack overflow occurs and the Information Store stops responding.



CAUSE
When a whole series of CRLF characters are copied at one time, the operation will fail if the CRLF characters do not fit in the output buffer. On the other hand, if the free space in the output buffer exceeds the margin (256 bytes), the buffer is not reallocated. This problem always occurs when the series of CRLF characters exceeds the buffer size (4096 bytes = 2048 CRLF pairs), and in certain circumstances, it may occur with as little as 128 CRLF pairs, or with any number in between.
