I'm using Wine 1.0 on Puppy Linux 3.01 I wrote an application with a http-server and a socket-server for windows and I like to use this on linux. (Delphi with Indy components) My application works fine on windows without any memory leak. But running with wine the VmRSS-value is permanently increased. I use following bash-script to check this: Code: while true; do cat /proc/"`pidof tcpc`"/status|grep -E "VmRSS";sleep 5; done Result: VmRSS: 4084 kB VmRSS: 4084 kB VmRSS: 4084 kB VmRSS: 4084 kB VmRSS: 4104 kB VmRSS: 4104 kB VmRSS: 4108 kB VmRSS: 4108 kB VmRSS: 4108 kB VmRSS: 4108 kB VmRSS: 4108 kB VmRSS: 4112 kB VmRSS: 4112 kB .... If I stop the http-requests of the client-application the VmRSS-growth of my server-application stops too. I found, that opening and closing of a tcp-socket is the cause of memory growth. I detected that the api-function (used by indy components) winsock.shutdown(FLastsocket,1); is the cause of the memory leak. All other functions of my application work fine. Is there any solution ?
