I have observed that when tshark is left running it appears to use an ever
increasing amount of memory. For example

844 root      20   0 1621152 1.119g  10096 S  0.3 38.0   2:06.90 tshark -n
-s1600 -Y smtp


after restart

 2913 root      20   0  267328 134864  54640 S  0.0  4.4   0:05.76 tshark -n
-s1600 -Y smtp                                         

this results in tshark exhausting the memory on my VPS over a period of time
