Re: [jetty-discuss] out of memory error using GZIPOutputStream

[jian c. <che...@gm...>]

Hi,=20

I got more information regarding the memory issue. The stack trace is:

java.lang.OutOfMemoryError: (class: org/mortbay/http/EOFException)=20
=09at org.mortbay.http.BufferedOutputStream.flush(BufferedOutputStream.java=
:206)
=09at org.mortbay.util.ByteBufferOutputStream.ensureSpareCapacity(ByteBuffe=
rOutputStream.java:357)

=09at sun.nio.cs.StreamEncoder$CharsetSE.implWrite(Unknown Source)
=09at sun.nio.cs.StreamEncoder.write(Unknown Source)

So, could it be a jetty issue?

Thanks,
