Hi Boris, I got it again and I guess it has something to do with using Netbeans.
Huhh ? Yes, Netbeans creates many but small shared memory blocks. I can't find any limit here for the number of shmem blocks nor for a max memory usage. But somehow it seems limited to 4096 chunks. I just experienced a garbled Kmail window (when opening a new window for a reply). I quick check with ipcs in a console says: $ ipcs -m|grep -c ^0x 4096 I closed Kmail and Netbeans, restarted Kmail and now: $ ipcs -m|grep -c ^0x 8 I use the original Oracle Netbeans download, Version 8.0.2. Well, maybe it is not Netbeans but simply Java (OpenJDK 8 here) - I can't say. However, there seems to be a shmem limit since a few weeks that hasn't been there before. Any idea how to proceed ?
