I am running a 100% vanilla 1.5.1 server. I get - as soon as someone joins - tons of these here:
java.io.IOException: Input/output error at java.io.RandomAccessFile.write(Native Method) at java.io.RandomAccessFile.writeInt(Unknown Source) at acg.a(SourceFile:307) at acg.a(SourceFile:249) at ach.close(SourceFile:230) at java.util.zip.DeflaterOutputStream.close(Unknown Source) at java.io.FilterOutputStream.close(Unknown Source) at acj.a(SourceFile:137) at acj.c(SourceFile:125) at akv.b(SourceFile:29) at akv.run(SourceFile:22) at java.lang.Thread.run(Unknown Source)
There is enough space on the harddisk, so that cannot be the issue. Any idea what could be wrong?
