Hi Eduardo & List! Nope, the problem isn't related to this but it's a coding problem in a way : to be able to *zip the dump file we first need... to build that "file", ie to store the whole dump informations in memory. For big databases/tables it may lead either to exceed the maximum allowed time to execute a php script, either to exceed the maximum allowed memory usage for a thread. The possible fix, at least for the second kind of problem, would be to not store dump informations but send them to the browser immediatly as soon as the user want these statements to be displayed on screen of put in a non- *zipped file (this is the "old method") and to keep the "new method" in the other cases.
