RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

2. Running one FtpClient on a PC, login the vsftpd server,and upload a file (more than 500MB)
3.Running another FtpClient on the same PC, login the vsftpd server, and upload the same file to the same directory of the server.

Actual results:
The second FtpClient just waiting and waiting...

Expected results:
The second FtpClient may recived one Code 550 or 450： File is not available


Additional info:
1. Running two or more FtpClients on different PC, expect the first one is uploading file ,the rest are all waiting and waiting...
2.Try other kinds of FtpClients, like 8uftp.exe, FlashXP.exe，the results are all the same.
3.While use Windows Server 2003 as a server. the rest FtpClients received an error "The process cannot access the file because it is being used by another process" immediately.

in the current release, Red Hat is unable to address this
request at this time.

Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.

I didn't reproduce the issue. I tested ftp client as well as lftp. Both clients was served by vsftpd as intended.

The client #2 is waiting till end of the upload of the client #1 then continues the upload of the client #2.

It's nice to see using lftp. The client #1 displays increasing percentage of data transfer. The client #2 displays 0% during the upload of the client #1. This percentage starts increasing when the upload of the client #1 is finished.

I tested it with 0.8 GB file.

Resolution -> closing 'notabug'.
