Hi, The attached program shows that some pipes used for executing subprocesses are not closed when they are no longer needed. This will cause a "too many open files" error in a long run.
I am afraid that FileDescriptor sync_fd in libraries/javalib/kaffe/lang/UNIXProcess.java has something to do with this problem. import java.io.*; public class TestProcess { public static void main(String[] args) throws Exception { for (int i=0; i < 10; i++) { Process p = null; InputStream pi = null; InputStream pe = null; OutputStream po = null; try { p = (Runtime.getRuntime()).exec(args); pi = p.getInputStream(); po = p.getOutputStream(); pe = p.getErrorStream(); p.waitFor(); } finally { try { if (pi != null) pi.close(); } catch (Exception _) {} try { if (po != null) po.close(); } catch (Exception _) {} try { if (pe != null) pe.close(); } catch (Exception _) {} } } while (true) {} } } bash$ kaffe TestProcess sh -c 'echo a' & [1] 3193 bash$ ls -al /proc/3193/fd total 0 dr-x------ 2 ito ito 0 Jun 7 13:39 . dr-xr-xr-x 3 ito ito 0 Jun 7 13:39 .. lrwx------ 1 ito ito 64 Jun 7 13:39 0 -> /dev/pts/8 lrwx------ 1 ito ito 64 Jun 7 13:39 1 -> /dev/pts/8 l-wx------ 1 ito ito 64 Jun 7 13:39 13 -> pipe:[45332619] l-wx------ 1 ito ito 64 Jun 7 13:39 14 -> pipe:[45332623] l-wx------ 1 ito ito 64 Jun 7 13:39 15 -> pipe:[45332627] l-wx------ 1 ito ito 64 Jun 7 13:39 16 -> pipe:[45332631] l-wx------ 1 ito ito 64 Jun 7 13:39 17 -> pipe:[45332635] l-wx------ 1 ito ito 64 Jun 7 13:39 18 -> pipe:[45332639] l-wx------ 1 ito ito 64 Jun 7 13:39 19 -> pipe:[45332643] lrwx------ 1 ito ito 64 Jun 7 13:39 2 -> /dev/pts/8 l-wx------ 1 ito ito 64 Jun 7 13:39 20 -> pipe:[45332647] l-wx------ 1 ito ito 64 Jun 7 13:39 21 -> pipe:[45332651] l-wx------ 1 ito ito 64 Jun 7 13:39 22 -> pipe:[45332655] lr-x------ 1 ito ito 64 Jun 7 13:39 3 -> pipe:[45332614] l-wx------ 1 ito ito 64 Jun 7 13:39 4 -> pipe:[45332614] lr-x------ 1 ito ito 64 Jun 7 13:39 5 -> /home/ito/javatest/TestProcess.class _______________________________________________ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
